Energy mix a term? Everything on electricity will not work. People still buy new cars that run on gasoline and diesel.
Of course everything works on electricity. But no one claims that this has to happen immediately. We are talking about nationwide infrastructure here; it is not there overnight. Transitions have to be managed.
But it is important to start somewhere to initiate this change over decades!
It's like the criticism that e-cars are bad because the charging infrastructure is missing. Was there already a network of gas stations when the first vehicles hit the road? No, it grew. Sometimes there are too many cars, sometimes too many gas stations, etc., in the long run, it balances out. You have to endure the intermediate states.
Who actually says that gas, gasoline, and diesel could not be burned centrally and used to generate electricity? That is why pipelines and gas turbine power plants are still needed today (which, by the way, can be converted to biogas or H2). This is called transition technology.
A gasoline engine throws away 70% of the energy in the fuel as heat. That is incredibly inefficient. Convert that into electricity and run e-cars with it. This is not the final goal, but for the transition, it is legitimate and practical.
Even Greta says nuclear power is good. Because without secure supply, no change will be accepted. Exactly right. It's a bitter pill but better than burning coal.
Extremists who say "shut everything down immediately, replace everything, throw everything away," etc., are just crazy and unrealistic, but that does not make the concern itself untrue.
But a gas heating system with photovoltaics and collectors is certainly anything but climate hostile.
Photovoltaics initially have nothing to do with gas heating.
The (solar thermal) collectors are at least unfriendly to the wallet, they really never pay off.
And of course, a heat pump consumes less climate-damaging energy than burning gas, the figures have already been mentioned here.
And running a heat pump but flying overseas twice a year is hypocritical climate policy.
That is primarily whataboutism, as it is called nowadays.
One thing has nothing to do with the other, and just because one thing is bad, the other does not have to be bad or remain bad.
There is undoubtedly a lot of work and many cogs that can (and must) be turned.
What is important is to start.
Maybe not with drinking straws, dear EU, that is just greenwashing.
The whining about our industries, which were important for the last decades, also gets on my nerves.
People cling to past successes, although today, even a moderately developed country can build cars, burn coal, or produce chemicals. There is no exclusivity anymore.
But the climate change issue is a growth market. Instead of checking panel gaps on cars, we should invest there. Then we have the knowledge and technology to sell worldwide. In the growth market digitization, we have essentially already lost.
THAT is Germany’s strength to be used, not a run-of-the-mill product that today already comes 80% from the Far East and is at best assembled in Germany.
Where do we start, where do we stop?
We start everywhere and stop when we are finished or dead.
One kWh of electricity still had over 460 g/kWh CO2 in 2018 (source: UBA) (gas 202g/kWh). That will certainly decrease when the share of renewable electricity generation rises and coal’s share falls, but we will still need fast-starting gas power plants for grid stabilization in 2038 and coal will only really be completely banned by 2038. So the CO2 share in the power mix will not fall to zero in the next 20 years (or even 50).
As you said yourself, you can calculate anything the way you want.
Taking the old power mix and using the worst heat pump can be one tactic.
But that is quite far from reality.
If you also consider that the poorly adjusted heat pump breaks down more often on average...
I see.
I don’t know how the ban will be implemented in Austria, but if, for example, all gas heaters had to be replaced at once, this would be worse for the environmental balance than letting the gas heaters run their normal lifespan first.
I know nothing about the ban in Austria either, and it doesn’t matter.
But take a look at how oil heating was dealt with in Germany (or recently old stoves/fireplaces), that was not long ago.
First, there are bans for new buildings. Then transition periods, hardship regulations. And at the latest when Erna dies and the house changes owner, the replacement obligation is active. Then it’s over.
It should also be socially acceptable. That’s why you have to start early to hit the brakes so that there is an end in sight. The paths are nevertheless long.
Well summarized. Whoever wants to heat economically now takes the gas boiler and converts in 20 years. However, due to lack of a gas connection, I also have a heat pump.
The decision was taken away from me too. In a system comparison, I might also have gone for gas because of the investment. Building budgets are simply limited.
Today, I think differently. CO2 pricing has started and even the CDU path is pre-marked. It will be accelerated, but even if it remains as it is now, every year 3-7 cents will be added to fuel. Every year 15-20% on the gas price for the house. At the same time, they want to rein in electricity prices.
But I believe that if I search long enough in your posts, I will find typical, blanket criticisms of photovoltaics and e-cars.
Now you yourself sit in an e-car and enjoy it, photovoltaics are planned.
Never say never ;-)
